  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/xe: Add bounds check on pat_index to prevent OOB kernel read in madvise  When user provides a bogus pat_index value through the madvise IOCTL, the xe_pat_index_get_coh_mode() function performs an array access without validating bounds. This allows a malicious user to trigger an out-of-bounds kernel read from the xe-\u003Epat.table array.  The vulnerability exists because the validation in madvise_args_are_sane() directly calls xe_pat_index_get_coh_mode(xe, args-\u003Epat_index.val) without first checking if pat_index is within [0, xe-\u003Epat.n_entries).  Although xe_pat_index_get_coh_mode() has a WARN_ON to catch this in debug builds, it still performs the unsafe array access in production kernels.  v2(Matthew Auld) - Using array_index_nospec() to mitigate spectre attacks when the value is used  v3(Matthew Auld) - Put the declarations at the start of the block  (cherry picked from commit 944a3329b05510d55c69c2ef455136e2fc02de29)",
